Home maintenance can be hard work. As soon as the fence has been put up, the window frames need sanding. Just when the garden is finally taking shape, the exterior walls need repainting. Owning and keeping a beautiful home takes hard work, but is well worth the effort. A massive part of home maintenance is protecting your building from dampness. Universal Roofing is one of the key waterproofing companies in Johannesburg, and provides the products and services necessary to accomplish this.


Gauteng sees a few rainy days in winter, which extends from June to August. However, it is the summer months (November to March) that bring the consistent afternoon thundershowers and, sometimes, hail with them. After a sweltering morning, these dramatic storms are a welcome relief. But, they also take their toll on buildings.

Once cracks form in the walls and roofs of a building, moisture gets in. This is when major problems start creeping in. Moisture and damp damage can cause patches of discolouration where mould begins to form or where the paint is compromised. Green or black marks look unsightly and will decrease the value of your property.

If the dampness is left unresolved, it can start to seep into the actual structure of your home or office. Ceilings can sag under the weight of water pools, and will crack and rot in the presence of moisture when roofs have not been waterproofed properly. Damp that starts near the timber frames of doors and windows will soon spread to the wood and cause it to rot too. This means having to repair or, likely, replace all of these frames. When moisture gets into a home, wallpaper or paint peels off; and carpets and laminated floors can be damaged terribly.

It’s also necessary to waterproof foundations to protect them from rising damp. Continued leaks can cause the foundations to shift slightly, which creates cracks in the floors and walls.
